Method and device for determining time-domain resources, storage
medium, and system
Abstract
A method and device for determining time-domain resources, a
storage medium, and a system. The method comprises: receiving
allocation information of time-domain resources to be scheduled,
which is sent by a network device (S401), the time-domain resources
to be scheduled comprising time-domain resources for performing
channel transmission; determining time-domain positions
corresponding to the time-domain resources to be scheduled
according to a set determining rule and uplink and downlink
time-domain resource configuration information and the allocation
information (S402); and performing, by means of the time-domain
resources to be scheduled, channel transmission according to the
time-domain positions corresponding to the time-domain resources to
be scheduled (S403). The condition of failure to transmit a channel
by a terminal in a short time period due to a conflict with
time-domain configuration information when the terminal performs
channel transmission is avoided, signaling overheads when the
terminal performs channel transmission with the base station are
reduced, and the increase of the probability of erroneous detection
caused by repeated transmission of control signaling is also
avoided.

CROSS-REFERENCE TO RELATED APPLICATIONS
This application is the US National Stage of PCT Application No.
PCT/CN2018/103458, filed Aug. 31, 2018, which claims priority to
PCT Application No. PCT/CN2017/101786, filed on Sep. 14, 2017, and
named after "METHOD AND DEVICE FOR DETERMINING TIME-DOMAIN
RESOURCES, STORAGE MEDIUM, AND SYSTEM", the contents of which are
hereby incorporated by reference in its entirety.
TECHNICAL FIELD
The disclosure relates to the technical field of wireless
communications, and more particularly to a method and device for
determining a time-domain resource, a storage medium and a
system.
BACKGROUND
With the development of communication technologies, researches on
5th generation mobile networks (5G) have been made. Radio access of
5G is called new radio (NR). Since 5G is required to support
ultrahigh data transmission rate, massive data connections and
relatively low data transmission delay, a 5G NR system, compared
with long term evolution (LTE) system, may not only implement
resource scheduling and allocation in units of a slot, like the LTE
system, but also implement resource scheduling and allocation in
units of a symbol in a slot to improve resource allocation
flexibility and reduce the data transmission delay. The resource
scheduling and allocation in units of a symbol may be called
symbol-level resource scheduling and allocation.
In the 5G NR system, a 5G base station, i.e., a gNB, may perform
symbol-level scheduling on a time-domain resource for transmitting
a channel, and may also dynamically or semi-persistently perform
symbol-level configuration on the time-domain resource. Therefore,
a conflict between time-domain resource scheduling information and
time-domain resource configuration information of the gNB may cause
the condition that a terminal may not transmit a channel within a
short period of time.

the time-domain resource to be scheduled according to the rule
predetermined with a base station to make the determined
time-domain position is consistent with scheduling information
obtained after the base station adjusts the time-domain resource to
be scheduled, so that the condition that the terminal may not
transmit a channel within a short period of time due to a conflict
between the time-domain resource configuration information and the
time-domain resource scheduling information during channel
transmission of the terminal is avoided, a signaling overhead
during channel transmission of the terminal and the base station is
also reduced, and an increase in the probability of false detection
caused by repeated sending of control signaling is also
avoided.

DETAILED DESCRIPTION
In order to make the characteristics and technical contents of the
embodiments of the disclosure understood in more detail, the
embodiments of the disclosure will be described below in
combination with the drawings in detail. The drawings are only
adopted for description as references and not intended to limit the
embodiments of the disclosure.
Referring to FIG. 1, an atypical application scenario according to
an embodiment of the disclosure is illustrated. The scenario may
include a network device and a terminal device. The network device
may be an evolved node B (eNB) in an LTE system, may also be a gNB
in a 5G NR system and, of course, may also be another network
device capable of providing a function of accessing a mobile
communication network for the terminal device. The terminal device
may include a cell phone, a smart phone, a session initiation
protocol (SIP) phone, a laptop computer, a personal digital
assistant (PDA), a satellite ratio telephone, a global positioning
system, a multimedia device, a video device, a digital audio player
(for example, a moving picture experts group audio layer-3 (MP3)
player), a camera, a game console, a tablet or any other device
with a similar function. In addition, the terminal device may also
be called, by those skilled in the art, user equipment, a terminal,
a mobile station, a subscriber station, a mobile unit, a subscriber
unit, a wireless unit, a remote unit, a mobile device, a wireless
device, a wireless communication device, a remote device, a mobile
subscriber station, an access terminal, a mobile terminal, a
wireless terminal, a remote terminal, a handheld device, a user
agent, a mobile client, a client or some other proper terms.
In the application scenario illustrated in FIG. 1, during
multi-slot or slot aggregation scheduling, a base station may
configure a starting symbol and a terminating symbol for channel
transmission in each of multiple slots, thereby implementing
symbol-level configuration. In addition, the base station may also
perform symbol-level scheduling for the slots for channel
transmission. In embodiments of the disclosure, a channel to be
transmitted may include a data channel such as a physical downlink
shared channel (PDSCH) and a physical uplink shared channel
(PUSCH), and may also include a control channel such as a physical
downlink control channel (PDCCH) and a physical uplink control
channel (PUCCH). For describing the technical solutions of the
embodiments of the disclosure clearly, descriptions are made
preferably with a DL data channel such as a PDSCH as an example in
the embodiments of the disclosure. It is to be understood that
those skilled in the art may apply the technical solutions of the
embodiments of the disclosure to channels of other types under the
guidance of the DL data channel.
A conflict between symbol-level scheduling and symbol-level
configuration of a time-domain resource such as a slot may make it
impossible for a terminal to transmit a channel within a short
period of time. A specific conflict conditions may at least include
the following two examples.
First Example
As illustrated in FIG. 2, for example, a channel to be transmitted
is a DL data channel such as a PDSCH. A gNB schedules part of
symbol resources in each of four slots, i.e., a slot 0, a slot 1, a
slot 2 and a slot 3, to transmit the DL data channel. Each slot has
a length of 14 symbols, but not all symbols in each of the four
slots are required to be occupied when the four slots are scheduled
to transmit the PDSCH. On the other hand, the gNB, when perform
time-domain resource symbol-level configuration for a terminal,
configures all the symbols in the slot 2 for transmission of a UL
channel, as illustrated in dotted blocks in FIG. 2. In such a case,
scheduled resources in the slot 2 may wholly conflict with
configured resources in the slot 2, like a conflict region filled
with cross lines in FIG. 2.
Second Example
As illustrated in FIG. 3, for example, a channel to be transmitted
is a DL data channel such as a PDSCH. A gNB schedules part of
symbol resources in each of four slots, i.e., a slot 0, a slot 1, a
slot 2 and a slot 3, for transmission. Each slot has a length of 14
symbols, but not all symbols in each of the four slots are required
to be occupied when the four slots are scheduled to transmit the
PDSCH. On the other hand, the gNB, when perform time-domain
resource symbol-level configuration for a terminal, configures part
of symbols in the slot 2 for transmission of a UL channel, as
illustrated in dotted blocks in FIG. 3. In such a case, part of
symbols of scheduled resources in the slot 2 may conflict with
configured resources in the slot 2, like a conflict region filled
with cross lines in FIG. 3.
The specific conflict condition is not limited to the two examples.
It is to be pointed out that a base station confronted with the
above-described conflicts, for solving the conflicts, may adjust a
time-domain resource to be scheduled during time-domain resource
scheduling to avoid the conflicts. However, the base station, after
adjusting the time-domain resource to be scheduled, is required to
notify a terminal of a scheduling state of the adjusted time-domain
resource, which may bring a high signaling overhead. Moreover, when
the base station is required to notify, through control signaling,
the terminal of adjustment of time-domain resource scheduling for
many times, a false detection probability of the terminal for the
control signaling may also be increased. According to the technical
solutions of the embodiments of the disclosure, after the base
station adjusts the time-domain resource to be scheduled, the
signaling overhead in notifying the terminal may be reduced, and
detection reliability of the control signaling may be improved.
Embodiment 1
Referring to FIG. 4, a method for determining a time-domain
resource provided in the embodiment of the disclosure is
illustrated. The method may be applied to a terminal. The method
may include the following operations.
At block S401, allocation information for scheduling a time-domain
resource is received from a network device.
The time-domain resource to be scheduled includes a time-domain
resource required for channel transmission.
At block S402, a time-domain position corresponding to the
time-domain resource to be scheduled is determined according to a
preset rule, based on UL and DL time-domain resource configuration
information and the allocation information.
At block S403, channel transmission is performed through the
time-domain resource to be scheduled based on the time-domain
position corresponding to the time-domain resource to be
scheduled.
It is to be explained that a channel may include a data channel
such as a PDSCH and a PUSCH, and may also include a control channel
such as a PDCCH and a PUCCH.
It can be understood that the preset rule may be a rule
predetermined by negotiation between the terminal and the network
device such as a gNB. The gNB, in case of a conflict between
scheduling of a time-domain resource and configuration of the
time-domain resource, may adjust the time-domain resource to avoid
the conflict. A specific manner or means in which the gNB adjusts
the time-domain resource to be scheduled may be described through
the rule. Therefore, the terminal, after obtaining the preset rule,
may make the same adjustment like the gNB. Thus, the gNB, after
adjusting a scheduling of the time-domain resource, is not required
to notify the terminal, and a signaling overhead between the
terminal and the gNB is reduced.
For the technical solution illustrated in FIG. 4, in a possible
implementation, the allocation information for scheduling the
time-domain resource may be carried in downlink control information
(DCI). It can be understood that the DCI may be dynamically
configured such that the gNB may timely transport the allocation
information to the terminal and the terminal may timely determine
the position of the time-domain resource to be scheduled to avoid
occurrence of the conflict.
For the technical solution illustrated in FIG. 4, in a possible
implementation, the method may further include that: the UL and DL
time-domain resource configuration information is received from the
network device. The UL and DL time-domain resource configuration
information includes at least one of slot-level position
information or symbol-level position information of an available
time-domain resource. It is to be explained that information used
to characterize the position of the time-domain resource in units
of a slot is called the time-level position information of the
time-domain resource and information used to characterize the
position of the time-domain resource in units of a symbol is called
the symbol-level position information of the time-domain
resource.
Specifically, the UL and DL time-domain resource configuration
information may be predefined information. The UL and DL
time-domain resource configuration information may also be carried
in at least one of radio resource control (RRC) signaling or the
DCI. During a specific implementation, the UL and DL time-domain
resource configuration information may be at least one of frame
structure information or a slot format indicator (SFI).
For the technical solution illustrated in FIG. 4, the allocation
information for scheduling the time-domain resource is not
scheduling information obtained after the gNB adjusts the
time-domain resource to be scheduled but description information of
the time-domain resource to be scheduled. The terminal, after
obtaining the description information of the time-domain resource
to be scheduled, determines the time-domain position corresponding
to the time-domain resource to be scheduled according to the
obtained rule determined by negotiation with the gNB, so that the
time-domain position, finally determined by the terminal,
corresponding to the time-domain resource to be scheduled is
consistent with the scheduling information obtained after the gNB
adjusts the time-domain resource to be scheduled. Therefore, the
gNB is not required to notify the terminal of the scheduling
information obtained after the time-domain resource to be scheduled
is adjusted in a channel transmission process, the signaling
overhead between the gNB and the terminal in the channel
transmission process is reduced, and an increase in the probability
of false detection caused by repeated sending of control signaling
is also avoided.
Therefore, in the embodiment, the allocation information for
scheduling the time-domain resource atypically includes the two
conditions for the description information of the time-domain
resource to be scheduled.
First Condition
The allocation information for scheduling the time-domain resource
includes information about a number of time-domain resources to be
scheduled. Specifically, the information about the number of the
time-domain resources to be scheduled includes at least one of
slot-level number information for the time-domain resources to be
scheduled or symbol-level number information for the time-domain
resources to be scheduled. It is to be explained that information
used to represent the number of the time-domain resources in units
of a slot is called the slot-level number information of the
time-domain resources and information used to represent the number
of the time-domain resources in units of a symbol is called the
symbol-level number information of the time-domain resource.
Correspondingly, when the allocation information for scheduling the
time-domain resource includes the information about the number of
the time-domain resources to be scheduled, referring to FIG. 5, the
operation in S402 that the time-domain position corresponding to
the time-domain resource to be scheduled is determined according to
the preset rule based on the UL and DL time-domain resource
configuration information and the allocation information may
include the following operations.
At block S4021A, time-domain resource candidates are determined for
time-domain resources to be scheduled based on the UL and DL
time-domain resource configuration information.
The number of the time-domain resource candidates is the same as
the number of the time-domain resources to be scheduled, and there
is no conflict between the time-domain resource candidates and the
UL and DL time-domain resource configuration information. The
conflict represents that a transmission direction indicated by the
UL and DL time-domain resource configuration information is
opposite to a channel transmission direction of the time-domain
resources to be scheduled.
At block S4022A, time-domain positions corresponding to the
time-domain resources to be scheduled are determined by filling the
time-domain resources to be scheduled into the time-domain resource
candidates.
In this example, in an implementation process, the operation of
filling the time-domain resources into the time-domain resource
candidates may preferably include that: the time-domain resources
to be scheduled are sequentially filled into the time-domain
resource candidates.
It is to be noted that the terminal, after obtaining the
information about the number of the time-domain resources to be
scheduled, may determine the time-domain resource candidates not
conflicting with the UL and DL time-domain resource configuration
information and then sequentially fill the time-domain resources to
be scheduled into the time-domain resource candidates. It can be
understood that, since the information about the number of the
time-domain resources to be scheduled may be at least one of the
slot-level number information or the symbol-level number
information, the terminal, when determining the time-domain
resource candidates, may also determine the time-domain resource
candidates in at least one of a slot-level or symbol-level manner.
The time-domain position corresponding to the time-domain resource
to be scheduled, determined by the terminal according to the
abovementioned process, is consistent with the scheduling
information obtained after the gNB adjusts the time-domain resource
to be scheduled, so that no signaling interaction is required to
notify the terminal of the adjusted scheduling information during
channel transmission, the signaling overhead between the gNB and
the terminal is reduced, and false detection probability increase
caused by repeated sending of the control signaling is also
avoided.
Second Condition
The allocation information for scheduling the time-domain resource
includes the information about the number of time-domain resources
to be scheduled and preselected position information for each
time-domain resource to be scheduled. It can be understood that the
number information may be at least one of slot-level or
symbol-level number information and the position information may be
at least one of slot-level or symbol-level position information and
elaborations are omitted herein.
Correspondingly, when the allocation information for scheduling the
time-domain resource includes the information about the number of
the time-domain resources to be scheduled and preselected position
information for the time-domain resources to be scheduled,
referring to FIG. 6, the operation in S402 that the time-domain
position corresponding to the time-domain resource to be scheduled
is determined according to the preset rule based on the UL and DL
time-domain resource configuration information and the allocation
information may include the following operations.
At block S4021B, a conflicting time-domain resource position is
determined, from preselected positions of time-domain resources to
be scheduled, based on the UL and DL time-domain resource
configuration information. The conflicting time-domain resource
position is a time-domain resource position, in the UL and DL
time-domain resource configuration information, with a channel
transmission direction opposite to a channel transmission direction
of the time-domain resources to be scheduled.
At block S4022B, the conflicting time-domain resource position in
the preselected positions is moved to a non-conflicting time-domain
resource position immediately following the conflicting time-domain
resource position. It can be understood that the non-conflicting
time-domain resource position is a time-domain resource position in
the UL and DL time-domain resource configuration information, with
a channel transmission direction the same as a channel transmission
direction of the time-domain resources to be scheduled.
At block S4023B, a preselected position, after the conflicting
time-domain resource position, in the preselected positions is
delayed according to a delay offset of the conflicting time-domain
resource position.
At block S4024B, whether a conflicting time-domain resource
position exists in the moved preselected positions or not is judged
according to the UL and DL time-domain resource configuration
information, if YES, S4022B is executed until no conflicting
time-domain resource position exists in the moved preselected
positions that are moved back and S4025B is executed, otherwise
S4025B is executed.
At block S4025B, time-domain positions corresponding to the
time-domain resources to be scheduled are determined by
sequentially filling the time-domain resources to be scheduled into
the moved preselected positions.
It can be understood that, when a preset position of the
time-domain resource to be scheduled in a slot conflicts with the
whole slot position in time-domain configuration information, the
conflicting preset position may be moved to the non-conflicting
slot position immediately following the conflicting slot position
and a preset position after the conflicting preset position is
delayed according to a delay offset of the conflicting preset
position, thereby avoiding occurrence of a conflict.
In addition, since the position information may be the symbol-level
position information, when the preset position of the time-domain
resource to be scheduled in the slot conflicts with part of the
slot positions in the time-domain configuration information, a
symbol at a conflicting preset position may be moved according to
the abovementioned process, a preset position after the conflicting
preset position is delayed according to a delay offset of the
conflicting preset position, and other non-conflicting preset
positions are not changed.
According to the time-domain resource determination method provided
in the embodiment, the terminal determines the time-domain position
corresponding to the time-domain resource to be scheduled according
to the rule predetermined with a base station to make the
determined time-domain position is consistent with scheduling
information obtained after the base station adjusts the time-domain
resource to be scheduled, so that the condition that the terminal
may not transmit a channel within a short period of time due to a
conflict between the scheduling information and the time-domain
configuration information during channel transmission of the
terminal is avoided, a signaling overhead during channel
transmission of the terminal and the base station is also reduced,
and false detection probability increase caused by repeated sending
of control signaling is further avoided.
Embodiment 2
Based on the same inventive concept of the abovementioned
embodiment, referring to FIG. 7, a flow of a method for determining
a time-domain resource provided in the embodiment of the disclosure
is illustrated. The method may be applied to a network device, for
example, a gNB. The method may include the following
operations.
At block S701, allocation information for scheduling a time-domain
resource is sent to a terminal.
The time-domain resource to be scheduled includes a time-domain
resource required for channel transmission. The allocation
information is used for the terminal to determine a time-domain
position corresponding to the time-domain resource to be
scheduled.
At block 702, channel transmission is performed through the
time-domain resource to be scheduled based on the time-domain
position corresponding to the time-domain resource to be
scheduled.
It is to be explained that the channel may include a data channel
such as a PDSCH and a PUSCH, and may also include a control channel
such as a PDCCH and a PUCCH.
It can be understood that the gNB, after finding a conflict
illustrated in FIG. 2 or FIG. 3 between scheduling information and
configuration information of the time-domain resource, may adjust
the scheduling information of the time-domain resource to avoid the
conflict. The terminal may determine position information of the
time-domain resource to be scheduled according to a rule
predetermined by negotiation with the gNB and make the same
adjustment like the gNB. That is, the time-domain position,
determined by the terminal, corresponding to the time-domain
resource to be scheduled is consistent with the scheduling
information obtained after the gNB adjusts the time-domain resource
to be scheduled. Therefore, the gNB may perform channel
transmission with the terminal through the time-domain resource to
be scheduled based on the time-domain position corresponding to the
time-domain resource to be scheduled to avoid the condition that
the terminal may not transmit the channel within a short period of
time due to the conflict between the scheduling information and the
configuration information. Further, the gNB is not required to
notify the terminal of the adjustment for the time-domain resource
to be scheduled, which can reduce a signaling overhead between the
terminal and the gNB and also avoid false detection probability
increase caused by repeated sending of control signaling.
In a possible implementation, the allocation information for
scheduling the time-domain resource may be carried in DCI. It can
be understood that the DCI may be dynamically configured such that
the gNB may timely transport the allocation information to the
terminal and the terminal may timely determine the position of the
time-domain resource to be scheduled to avoid occurrence of the
conflict.
In a possible implementation, the method may further include that:
UL and DL time-domain resource configuration information is sent to
the terminal. The UL and DL time-domain resource configuration
information includes at least one of slot-level position
information or symbol-level position information of an available
time-domain resource. It is to be explained that information
configured to represent a position of the time-domain resource in
units of a slot is called the slot-level position information of
the time-domain resource and information configured to represent a
position of the time-domain resource in units of a symbol is called
the symbol-level position information of the time-domain
resource.
Specifically, the UL and DL time-domain resource configuration
information may be predefined information. The UL and DL
time-domain resource configuration information may also be carried
in at least one of RRC signaling or the DCI. During a specific
implementation, the UL and DL time-domain resource configuration
information may be at least one of frame structure information or
an SFI.
For the technical solution illustrated in FIG. 7, it is to be noted
that the allocation information for scheduling the time-domain
resource is not scheduling information obtained after the gNB
adjusts the time-domain resource to be scheduled but description
information of the time-domain resource to be scheduled. The
terminal, after obtaining the description information of the
time-domain resource to be scheduled, determines the time-domain
position corresponding to the time-domain resource to be scheduled
according to the obtained rule determined by negotiation with the
gNB, so that the time-domain position, finally determined by the
terminal, corresponding to the time-domain resource to be scheduled
is consistent with the scheduling information obtained after the
gNB adjusts the time-domain resource to be scheduled. Therefore,
the gNB is not required to notify the terminal of the scheduling
information obtained after the time-domain resource to be scheduled
is adjusted in a channel transmission process, and the signaling
overhead between the gNB and the terminal in the channel
transmission process is reduced. As an atypical example, the
allocation information for scheduling the time-domain resource
includes information about the number of time-domain resources to
be scheduled; or, the allocation information for scheduling the
time-domain resource includes the information about the number of
the time-domain resources to be scheduled and information about a
preselected position of each time-domain resource to be
scheduled.
According to the time-domain resource determination method provided
in the embodiment, the network device sends the allocation
information for scheduling the time-domain resource to the terminal
to enable the terminal to determine the time-domain position
corresponding to the time-domain resource to be scheduled.
Therefore, the gNB may perform channel transmission with the
terminal through the time-domain resource to be scheduled based on
the time-domain position corresponding to the time-domain resource
to be scheduled to avoid the condition that the terminal may not
transmit the channel within a short period of time due to the
conflict between the scheduling information and the configuration
information. Further, the gNB is not required to notify the
terminal of the adjustment for the time-domain resource to be
scheduled, which can reduce a signaling overhead between the
terminal and the gNB and also avoid false detection probability
increase caused by repeated sending of control signaling.
Embodiment 3
Based on the same inventive concept of the abovementioned
embodiments, the technical solutions of the abovementioned
embodiments are described in the embodiment with the following
specific examples. It is to be noted that, in all the following
specific examples, descriptions are made with adoption of a
time-domain resource to be scheduled for transmission of a DL data
channel such as a PDSCH as an example and a network device is, for
example, a gNB. It can be understood that, during a practical
application, the time-domain resource to be scheduled may also be
configured to transmit a UL data channel such as a PUSCH, and a UL
or DL control channel such as a PDCCH or a PUCCH. There are no
elaborations made thereto in the specific examples of the
embodiment.
Specific Example 1
For example, as illustrated in FIG. 8, it is to be noted that the
first line in FIG. 8 is graphical information of FIG. 8.
The gNB sends allocation information for scheduling the time-domain
resource to a terminal. The allocation information may be a DL
grant. The allocation information includes information about the
number of time-domain resources to be scheduled, as illustrated in
the gray block in the second line in FIG. 8. The information about
the number of the time-domain resource to be scheduled may be
slot-level information and may also be symbol-level information, so
that the total number of the time-domain resources to be scheduled
is two slots and a plurality of additional symbols. In the
embodiment, the plurality of symbols are, for example, 10 symbols.
Therefore, the terminal, after obtaining the information about the
number of the resources to be scheduled, determines time-domain
resource candidates according to known UL and DL time-domain
resource configuration information, as illustrated in the
distribution of the gray blocks in the third line in FIG. 8. It is
to be noted that the UL and DL time-domain resource configuration
information may specifically be DL and UL assignment. It can be
seen from the UL and DL time-domain resource configuration
information illustrated in the fourth line in FIG. 8 that a
plurality of last symbols of a slot 1 and the whole slot 2 are
time-domain resource regions configured to transmit a UL channel or
others and may conflict with transmission of the PDSCH. Therefore,
the terminal, when determining the time-domain resource candidates,
may avoid the conflicting regions. Then, the terminal sequentially
distributes the time-domain resources to be scheduled into the
time-domain resource candidates, thereby determining time-domain
positions of the time-domain resources configured to transmit the
PDSCH.
Specific Example 2
For example, as illustrated in FIG. 9, it is to be noted that the
first line in FIG. 9 is graphical information of FIG. 9.
The gNB sends allocation information for scheduling the time-domain
resource to a terminal. The allocation information may be a DL
grant. The allocation information not only includes information
about the number of time-domain resources to be scheduled, but also
includes information about a preselected position of each
time-domain resource to be scheduled, as illustrated in the second
line in FIG. 9. The terminal, after receiving the allocation
information, may compare the information about preselected
positions of the time-domain resources to be scheduled and known UL
and DL time-domain resource configuration information in the fourth
line in FIG. 9 to find that a slot 2 is a time-domain resource
region configured to transmit the UL channel or others and may
conflict with transmission of the PDSCH. Therefore, the terminal
moves a conflicting preselected position in the slot 2 to a
non-conflicting position, i.e., a slot 3, closest to the slot 2 and
delays a preselected position after the conflicting position
according to a delay offset of the conflicting preselected position
to avoid occurrence of a conflict, as illustrated in the third line
in FIG. 9. After the preselected positions are moved, the terminal
sequentially fills the time-domain resourced to be scheduled into
the moved preselected positions, thereby determining the
time-domain positions corresponding to the resources to be
scheduled.
Specific Example 3
For example, as illustrated in FIG. 10, it is to be noted that the
first line in FIG. 10 is graphical information of FIG. 10.
Like specific example 2, the gNB sends allocation information for
scheduling the time-domain resource to a terminal. The allocation
information may be a DL grant. The allocation information not only
includes information about the number of time-domain resources to
be scheduled, but also includes information about a preselected
position of each time-domain resource to be scheduled, as
illustrated in the second line in FIG. 10. The terminal, after
receiving the allocation information, may compare the information
about preselected positions of the time-domain resources to be
scheduled and known UL and DL time-domain resource configuration
information illustrated in the fourth line in FIG. 10. However, in
the specific example, a last part of a slot 2 conflicts with part
of preset positions of the time-domain resources to be scheduled,
the terminal may move symbols at a conflicting preset position to a
closest non-conflicting slot, delay a preset position after the
conflicting preset position according to a delay offset of the
conflicting preset position and keep other non-conflicting preset
positions unchanged to avoid occurrence of a conflict, as
illustrated in the third line in FIG. 10. After the preselected
positions are moved, the terminal still sequentially fills the
time-domain resources to be scheduled into the moved preselected
positions according to the process in specific example 2, thereby
determining the time-domain position corresponding to the resource
to be scheduled.
Specific implementation of the technical solutions of the
abovementioned embodiments are described above with the three
specific examples in detail. It can be seen that the terminal may
determine the time-domain position of the time-domain resource to
be scheduled based on the allocation information sent by the gNB,
thereby avoiding occurrence of the conflict. Moreover, since a
determination result of the terminal is consistent with a result
obtained by scheduling adjustment of the gNB, the terminal, during
channel transmission with the gNB, is not required to learn an
adjustment result of a time-domain resource scheduling of the gNB
by signaling interaction, which reduces the signaling overhead and
also avoids an increase in the probability of false detection
caused by repeated sending of control signaling.
Embodiment 4
Based on the same inventive concept of the abovementioned
embodiments, referring to FIG. 11, a structure of a terminal 110
provided in the embodiment of the disclosure is illustrated, and
may include a receiving portion 1101, a determination portion 1102
and a first transmission portion 1103.
The receiving portion 1101 is configured to receive allocation
information for scheduling a time-domain resource from a network
device. The time-domain resource to be scheduled includes a
time-domain resource required for channel transmission.
The determination portion 1102 is configured to determine according
to a preset rule, a time-domain position corresponding to the
time-domain resource to be scheduled based on UL and DL time-domain
resource configuration information and the allocation
information.
The first transmission portion 1103 is configured to perform

resources to be scheduled, a conflicting time-domain resource
position based on the UL and DL time-domain resource configuration
information; here, the conflicting time-domain resource position is
a time-domain resource position, in the UL and DL time-domain
resource configuration information, with a channel transmission
direction opposite to a channel transmission direction of the

exists in the moved preselected positions or not according to the
UL and DL time-domain resource configuration information, if YES,
turn to S2 until no conflicting time-domain resource position
exists in the preselected positions that are moved and execute S5,
